CAPSULING DEVICE.

Specification of Letters Patent.

Patented Sept. 17', 1912.

Application filed June 22, 1912. Serial No. 707,645.

To all whom it may concern:

Be it known that I, OU'ITHBERT GENTLE, a subject of the King of England, residing at Dorche'ster, in the county of Sulfolk and State of Massachusetts, have invented a new and useful Improvement in Capsuling Devices, of which the following is a specification.

The present invention relates to devices for pressing capsules over the closed necks of filled bottles and .more particularly to an improvement upon the capsuling device illustrated and described in Letters Patent of Great Britain granted to Cuthbert Gentle and David Denholm, No. 1320 of 1891. The capsuling device disclosed in this patent comprises a suitable support, a hollow frustoconical chamber carried thereby, and a resilientring arranged to engage the peripheral walls of the interior of the chamber and roll thereon over a capsule loosely placed upon the closed neck of a bottle inserted into the chamber. This device efiectively pressed the capsule into position on quart bottles which are usually provided with long cylindrical necks and which for a number of years were the only bottles provided with capsules by the trade. In later years, however, it has become desirable to cap-' sule pint and half-pint bottles as well as quart bottles. But pint and half-pintbottles are made with short necks rising from wideshoulders. It was discovered that it is impossible tocapsule pint and half-pint bottles with the capsuling device described in the British patent hereinbefore referred to owing to the fact that the square shoulders on the bottles struck the end of the chamber before the rubber ring had completely rolled the capsule into position on the neck of the bottle.

The object of the invention is to produce a device adapted to effectively ca sule various styles of bottles whether provi ed withlong or short necks.

To this end the invention consists in the features and combinations ofv constructions hereinafter described and set-forth in the claims.

The various features of the present invention will be readily understood from an inspection of the accompanying drawing illustrating the referred form of the invention, in whicii,

Figure 1 is a side elevation of the capsuling device and showing a short necked bot tie with a fancy capsule loosely applied thereto about to be inserted into the chamber; Fig. 2 is a longitudinal sectional elevation through the chamber of the capsuling' device showing the extent to which the capsole is pressed into position by the resilient ring atthe time the shouldersof the bottle engage the chamber; and Fig. 3 is a sectional length of the chamber .is decreased,,-to increase the neck area over which the resilient ring rolls the capsule.

The illustrated embodiment \of the invention is provided with a pair of arms 1 and 3 arranged to embrace the ledge of a table and be clamped thereto by athumb screw 4:. The arm 2 carriesa suitable support for a hollow frusto-conical chamber 6 open atits wider base and closed atthe narrower base except for a small vent 7. (Fig; 2). The chamber 6 is formed' in sections 8 and 9, the section 8 being carried by the support 5, and the section 9 being arranged to tele-- scope upon the section 8. Coiled around the chamber with its ends soldered respectively to the sections 8 and 9 is a spring 10 consition. The section 9 is provided with a lip 11 which holds a resilient ring 12 in place .upon the peripheral walls of the interior of the chamber; I I i In using the device the neck of the bottle to which the capsule has been loosely,applied is forced into the opening in the ring -12. As the pressure continues the ring rolls along the interior wall of the chamber over the capsule on the neckof the bottle. (Fig. 2). As the ring rolls toward the narrower base of the frusto-conical chamber the pressure of the ring on the capsule increases until the capsule is pressed into the angle bead formed thereon at, which time the shoulders of the bottle strike the lip 11. Continued nzgssure on the bottle causes the section 9 to telescope on the section 8 a; list the tension of the spring 10 until limited by the lip 11 thus permit-tang the neck of the bottle to pass farther into the chamber and and down smooth upon the surface of the bottle. As soon as the pressure on' the bottle is relieved the spring 10 ushesthe are restored to the position of Fig. 1.-

. In capsulinglong necked bottles the neck detail showing the manner in which the.

between thesurface of the neck and the structed to hold the chamber in extended pothe ring to roll the capsule over the .bead

bottle away from the chamber an the parts is inserted into the chamber as in the caseof short necked bottles, but asthere is no shoulder to engage the lip 11 the neck may be pushed in until the capsule is rolled into position when the bottle maybe withdrawn,

It will be clear to those skilled in this class of devices and with the object of the f'perlpheral' walls of t e interior of the chainber, and means permitting one section of the chamber to telescope upon another 1 duringthe capsuling operation, substantially as de scribed, f w 2. A device for pressing capsules-over the closed neck of a bottle, having, in combination, a hollow chamberconsistingfof a plurality of'frusto-conical sections, a resil entring arranged to engage and roll along the peripheral walls of the interior of the chamber, and means permitting onesection of the chamber to telescope upon another under contact with the shoulders of a bottle as its neck is passed into the chamber for the capsuling operation, substantially as described.

3. A device for pressing capsules over the closed neck of a bottle, having, in combination, a hollow chamber, a resilient ring arranged to engage the peripheral .walls of the interior of the chamber and roll thereon over'the' closed neck of a bottle inserted into the chamber,- and means permitting the length of the chamber to be decreased to increase the neck area; overiwhich the ring rolls, substantially as described.

A deviceior pressing capsules over the closed neck of a bottle, having, in, combination, a support,+a hollow sectional chamber carried thereby, .a spring coiled around the exterior of the chamber and connected to eachof the sections, and a resilient ring arranged to engage and roll over the interior peripheral 'walls, of the chamber, substantially as described w r x 7:. v CUIIHBERT GENTLE. ;Witnesses:' v WGRAC Copies -01 this patent may be obtained'for five cents each, byaddressing the Commissioner of Patents,
